Contents: Dietitian vs Nutritionist
A Nutritionist is a health specialist who devotes professional activity to food and nutritional science, preventive nutrition, diseases related to nutrient deficiencies, and the use of nutrient manipulation to enhance the clinical response to human diseases. A Dietitian is an expert in food and nutrition. Dietitians help promote good health through proper eating. They also supervise the preparation and service of food, develop modified diets, participate in research, and educate individuals and groups on good nutritional habits .
In the US, a Registered Dietitian (RD) needs the following qualifications:
- a Bachelor's degree in nutrition or dietetics
- an internship for 6 to 12 months at a healthcare facility, foodservice company or nonprofit agency approved by the American Dietetic Association
- successful completion of a national exam conducted by the Commission on Dietetic Registration.
- Ongoing to retain their registration as a dietitian.
Nutritionists are not required to have any such qualifications. This means nutritionists have varying levels of education -- from someone with little or no education to an individual who has obtained a bachelor's, master's, or even a doctoral degree.

A Dietitian holding a Bachelor's degree in dietetics or related areas is legally regarded as the expert in nutrition and dietary related matters. On the other hand, a Nutritionist may or may not have any educational qualification and is not a legally protected term in most parts of the world.
